CHURN.

SPECIFICATION forming part of Letters Patent No. 645,476, dated March 13, 1900. Application led June 1'7, 1899. Serial No. 720,966. (No model.)

To all whom t may concern:

Be it known that I, Bassin KINGSLEY, Wife of William Kingsley,a citizen of the Dominion of Canada, residing at, South Vancouver, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Churns, of which the following is a specification.

My invention relates to improvements in that class of churns having their construction of barrel form, with the trunnions oppositely disposed therefrom, which rest in bearings in a suitable frame, whereby the churn When rotatedwill be turned endwise to the axis of the barrel.

The objects of my invention are, first, to construct the body of the churn of such a form-that its center part, which is in line with the axis of its movement, oers no space or area in which the cream therein will gather and not be properly agitated, as is the case with the churn. having a uniform contour of circumference and diameter at this point, and to construct such a body of a material that cannot impart any unwholesome taste or effect to the cream, and consequently to the butter; second, to provide a cover for the churn that is of a cheap and simple construction and that may be secured in a simple and eective manner, and, third, to arrange the bearings for the churn in lan adjustable manner, so that the crank-handle may be brought the desired height for the operator, and also to provide a means for holding the churn in an upright or an inverted position while the contents are poured therein or emptied therefrom, respectively. I attain these objects by the mechanism illustrated in the accompanying drawings, in Which- Figure 1 shows anelevation of my churn with the vessel for holding the cream sectioned lengthwise thereof. Fig. 2 is a plan of the churn. Fig. 3 is adetail ofthe device employed for locking the churn in any position desired, and Fig. 4 is a sectional detail of the vent-plug.

Similar numerals refer to different parts throughout all the views.

The churn 10 is preferably constructed of enameled iron or granite ware. The opposite sides of thisare fluted,which flutes are formed by concave channels 10, passing through the swell of the barrel-shaped body. Securely- The trunnions 11 at their point of bearing vare provided with V-shaped cones 11, which rest in the grooves in the bearings 12, designed t-o receive the same.- This prevents the churn from having lateral movement-on its bearings, which is a very important improvement over the old method.

The bearings 12 are blocks made to fit between the forks 13 and susceptible of being slipped up and down, and they are secured at the desired horizontal plane bybolts 19, having butterfly-heads thereon for turning the hand, threading through straps 20,Which inclose the blocks 12 and the forks'13. (See Fig. 3.)

The churn is turned as in the usual way by a crank-handle 21, secured to the end of the trunnions 11. The churn may be locked in .a horizontal, upright, or inverted position by a vertical slidable spring-holder 22, fixed to the upright 14 on the opposite side. This spring-holder 22 is secured to the upright 14 in its vertical movable position by straps 23 and when not in use is slipped below the trunnion 11; but when in use the square end of the said trunnion is passed through the opening 22 therein, which prevents the churn from being turned. Sufficient vertical movement is provided for the holder 22 to allow for the vertical adjustment of Athe churn, so that it may be locked at any point.

The open end of the churn 10, like the closed end, is of uniform diameter. The cover 24 is provided With an annular groove 24 to receive the rim of the body 10, and to make the joint tight a strip of cork or other like material is inserted and arranged to expose an even plane in the said groove. At the center of the cover 24 is a rigidly-fixed stud or bolt 25, on which is a screw-Wheel26, susceptible of being turned up or down as a nut, and

IOO

` are provided with depressions-29b, in which the ends of the bar 27 are received and held when the screw-wheel 2G is turned down tight.

The foregoing arrangement provides a very effective fastening and one that is cheap of construction.

30 indicates allight or sight pane inserted in one side -of the cover. This enables the operator to see the various conditions of the cream in the operation of churning the butter without the necessity of removing the cover, and at the opposite end of the churn 10 and iixed in its side is a nipple 3l. This is provided with a cap 32, threaded thereon, in the hollow of which is a piece of cork 33, so that when it is screwed up tight the opening will be effectively stopped. For an airvent a small aperture 32 is provided in the Wall of the cap. This, when the cap is turned back so that the cork 33 is lifted off its seat on the nipple, allows a suitable air-vent.

By reason of the fiutes l0a on the opposite sides of the barrel-framed vessel the cream will be prevented from gathering in cones on opposite sides in line with the axis of its Y movement, and consequently all parts of the matters in the churn will be uniformly agitated, whereas in the old style, as the churn is rotated, there is a zone on each side of the swell of the barrel that allows the cream to gather, and thereby considerable energy is wasted.

It is shown from the foregoing that although my churn is of similar pattern and is operated similar to churns now in the market of this class, there are improvements in the details of the kconstruction and the general arrangements which make my invention a complete and efiicient machine and give it superior advantage over others that are now in the market.

Having thus described my invention, what I claim, and desire to be protected in by Letters Patent, is-- l. A churn comprising a closable vessel of barrel form, said vessel being provided with concaved iutes orgrooves arranged with their planes parallel to each other and parallel to the axis of the vessel; trunnions projected from the sides thereof; a supporting-frame for the vessel; two bearings vertically adjustable upon the said frame, anda vertically-adj ustable detent adapted to engage with one of the trunnions of the vessel and hold it in different positions as speciiied.

2. A churn comprisin ga closable vessel having flutes down each side forming convexed.

ridges on the inner opposite sides; and a closure for such vessel having an annular groove therein to receive the open end ot' the vessel; diametrically-oppositely=arranged'levers hinged'at their outer ends to the iiuted sides of the vessel, said levers having their adjacent or inner ends turned upward to form hook members and near their outer ends bent to form fulcrums 29a; a bar loosely fixed upon a stud projected up centrally from the closure, said bar havingits ends engaging the adjacent ends of the levers and adapted when pressed down to force the levers tightly against the closure, and means for pressing the said bar down, all being arranged substantially as shown and described.

3. In a churn of the class described having the barrel form, parallel flutes on opposite sides thereof which form convex swells or ribs on the inner sides, trunnionsxed at the center of said ilutes, conical ridges on said trunnions, bearings arranged in forks having grooves for receiving the conical ridges,means for adjusting the bearings vertically, consisting of straps 20 embracing the bearings and the forks and set-screws taking through the straps and engaging one side of the forks all substantially, as and for the purposes set forth.

4:. In combination with a rigidly-braced frame having forked uprights and adjustable bearings arranged therein, a vessel having iiuted sides suitably mounted on trunnions which journal in said bearings, a vertical slidable holder 22 of elastic material having an angled opening at its upper end for receiving the angled end of one of the trunnions for holding the churn at rest at any desired position.

5. `In a churn of the character described, the combination with the churn-body; means for rotating it, and means for holding the said churn in different positions; a cover for the open end and means for hermetically sealing the said cover upon the said ends; of a ventnipple connected with the vessel near the end opposite the cover, said nipple having a removable cap provided with a vent an elastic washer Within the said cap, said cap, washer and vent in the said cap being so arranged that when the cap is screwed home the vent will be cut off from the nipple and when screwed outward to remove the elastic packing from the nipple the vent is brought into communication with the nipple, all being arranged substantiallyas described.
